Known fact: The smoother one is from @Formlabs Form 2 (SLA technology). It really is better in quality, but when I need big parts, or when I need a part quickly, @MakerBot (FDM technology) is a better solution. FDM use filaments, which are usually cheaper. They create infill structures to make the part cost less. SLA uses resins, which are more expensive, but distorting is harder, so it can be a better solution sometimes.
I 3D designed it using @SolidWorks .
